2.4 GHz Universal Frequency Counter with Ratio Function0 pages
Data Sheet
Frequency Counters
Models 1823A, 1856D
Model 1823A
The 1823A and 1856D are reciprocal 2.4 GHz
and 3.5 GHz frequency counters that are
microprocessor controlled. Their LED displays
can provide up to nine digits of resolution using
an external time base with a 10 s gate time. The
high accuracy, sensitivity, and versatility of these
counters make them an extremely valuable
instrument to scientists, engineers, and
communications technicians for a broad spectrum
of laboratory and service applications.
